Along with Conor, she crashed a wedding on Saturday (August 18), caused a big scene, then refused to leave when she was asked to by Victoria Gifford Kennedy, mother of the bride.

“They texted me an hour before the wedding and asked if they could come,” Vicki Kennedy said. “I responded with a very clear, ‘Please do not come.’ They came anyway. ... I personally went up to Ms. Swift, whose entrance distracted the entire event, politely introduced myself to her, and asked her as nicely as I could to leave. It was like talking to a ghost. She seemed to look right past me.”

The whole affair took place at the Fairmont Copley Plaza hotel, where Kyle Kennedy, the daughter of the late Michael Kennedy and Victoria Gifford Kennedy, was marrying Liam Kerr.

While Swift's publicist denies that she was unwanted at the wedding, sources at the hotel confirmed seeing Swift being asked to leave. And Vicki did admit that Conor Kennedy, Swift's beau, was invited. But he never sent an RSVP, and when he texted to say he was coming, she was opposed because she didn't want Swift's presence to distract from the wedding. They showed up anyway, and Swift was asked to pose for pictures and autographs with fans in the hotel lobby. They left briefly during dinner, but then came back and spent the rest of the night at the reception.
